此文源于unityManul（高版本）
1）生成assetbundle
[MenuItem("Assets/Build AssetBundles")] static void BuildAllAssetBundles() { string dir = "AB"; if (Directory.Exists(dir) == false) { Directory.CreateDirectory(dir); } BuildPipeline.BuildAssetBundles(dir, BuildAssetBundleOptions.ChunkBasedCompression, BuildTarget.StandaloneWindows64); }
2）同步本地加载
var myLoadedAssetBundle = AssetBundle.LoadFromFile(Path.Combine(Application.streamingAssetsPath, "myassetBundle"));//可以实全路径也可以是相对路径如 "AB/cc.dd" if (myLoadedAssetBundle == null) { Debug.Log("Failed to load AssetBundle!"); return; } var prefab = myLoadedAssetBundle.LoadAsset.<GameObject>("MyObject"); Instantiate(prefab);
3）异步本地加载
IEnumerator LoadFromMemoryAsync(string path) { AssetBundleCreateRequest createRequest = AssetBundle.LoadFromMemoryAsync(File.ReadAllBytes(path));// yield return createRequest; AssetBundle bundle = createRequest.assetBundle; var prefab = bundle.LoadAsset<GameObject>("MyObject"); Instantiate(prefab); }
问题：AssetBundle.LoadFromMemoryAsync(File.ReadAllBytes(path))中LoadFromMemoryAsync只要传入byte[]类型参数即可，而且在android中如果assetbundle放在streamingassets下file类是无法读取的，所以可以通过其他方法异步加载，如www类。加载到byte[]然后传给LoadFromMemoryAsync方法调用。异步方法还有更直接的方法如下。
4）WWW异步加载
此加载assetbundle的方法将被弃用
while (!Caching.ready) yield return null; var www = WWW.LoadFromCacheOrDownload("http://myserver.com/myassetBundle", 5); yield return www; if(!string.IsNullOrEmpty(www.error)) { Debug.Log(www.error); yield return; } var myLoadedAssetBundle = www.assetBundle; var asset = myLoadedAssetBundle.mainAsset;
如果存在本地，则LoadFromCacheOrDownload("http://myserver.com/myassetBundle", 5)中的http链接改为本地路径，但是路径前要加http://，或者采用类new System.Uri(本地路径).absoluteUri;获取相关相关uri路径。
5）UnityWebRequest方法
string uri = "file:///" + Application.dataPath + "/AssetBundles/" + assetBundleName; UnityEngine.Networking.UnityWebRequest request = UnityEngine.Networking.UnityWebRequest.GetAssetBundle(uri, 0); yield return request.Send(); AssetBundle bundle = DownloadHandlerAssetBundle.GetContent(request); GameObject cube = bundle.LoadAsset<GameObject>("Cube"); GameObject sprite = bundle.LoadAsset<GameObject>("Sprite"); Instantiate(cube); Instantiate(sprite);
6）加载Assetbundle内容
官方api中提供了众多方法，最基本的方法为abCube.LoadAsset<T>方法
AssetBundle abMat = AssetBundle.LoadFromFile(mat); AssetBundle abCube = AssetBundle.LoadFromFile(cubep); AssetBundle abSphere = AssetBundle.LoadFromFile(spherep); GameObject cube = abCube.LoadAsset<GameObject>("Cube"); Instantiate(cube); GameObject sphere = abSphere.LoadAsset<GameObject>("Sphere"); Instantiate(sphere);
7）通过打包的总文件获取依赖
AssetBundle assetBundle = AssetBundle.LoadFromFile(manifestFilePath);//打包的总文件位置 AssetBundleManifest manifest = assetBundle.LoadAsset<AssetBundleManifest>("AssetBundleManifest"); string[] dependencies = manifest.GetAllDependencies("cc.dd"); //获取cc.dd的所有依赖文件. foreach(string dependency in dependencies) { AssetBundle.LoadFromFile(Path.Combine(assetBundlePath, dependency)); }
